Of all the problems that Texas Sen. Ted Cruz has had to endure during the course of the Republican primary, nothing has been more of a burden than the reoccurring issue over his Canadian birth. While various lawsuits have been filed questioning Cruz's eligibility for president, the senator from the Lone Star State has been able to avoid major problems.

Canadian Cruz

Rafael Edward Cruz, better known as "Ted," was born in Calgary, Alberta, Canada on December 22, 1970. Cruz's father, Rafael, was born in Cuba, while his mother, Eleanor, was born in Delaware.

Though the United States Constitution requires that anyone running for president must be a "Natural Born Citizen," the document never detailsthe definition ofthe term. While the issue was assumed to be dead, Donald Trump brought Cruz's birther issue up during his most recent campaign stop, as reported by The Hill on April 23.

"You're registered as a Canadian citizen, he never knew he was a Canadian," Trump said about Cruz, while speaking to a crowd of supporters in Waterbury, Connecticut. Continuing, the billionaire real estate mogul went on to predict that if Cruz is nominated, "The first thing the Democrats are going to do is sue him on the basis that he’s not a naturalized citizen, he wasn’t born in the country."

Cruz and the SCOTUS

Various lawsuits have been filed against Cruz challenging his eligibility to run for president, but one has stood out above the rest.

As reported by Law Newz earlier this month, a lawsuit filed by Walter Wagner, a resident from Utah, has had his lawsuit appealed all the way to the Supreme Court. While the lawsuit has not been heard, and could very well be denied, it's "officially on the court docket for consideration to be heard." Cruz's legal team has until May 5 to respond to the legal action.

Primary status

Whether or not the birther lawsuit goes further, Cruz still has a fight on his hands heading into the Republican National Convention this July. With only 559 delegates to his name, Cruz is mathematically eliminated from clinching the party's nomination, with Trump and his 845 delegates the odds on favorite to walk out of Cleveland, Ohio the winner.
